Good to see you wrote: "Removed the clips from the mounting surfaces". By this statement I would think you're speaking of the 2 circular clips on the wheel studs used to keep the rotors in place on the assembly line. (Note: If this implies the original tire shop did not remove these clips when they installed your new wheel/tire package, then an inexperienced wheel/tire installer did the original wheel install.)
Factory wheels have relief cutouts to accomidate the stud clips, but your new Forgestar wheels do not. Definitely a source of viberation and wheel wobble.
Next, as the driver you can help to diagnose the location of the viberation, either front or rear wheel(s).
If the viberation seems to be felt in the seats, and/or windshield mounted rear view mirror, this would tipically indicate a Rear wheel balance problem.
If the viberation seems to be felt in the steering wheel and/or the brake pedal* this would tipically indicate a front wheel balance problem.
(* footnote: Front wheel balance felt in brake pedal with very light foot pressure. Not to be confused with warped front rotors felt with normal foot brake pedal pressure.)
I'm leaning toward, (hoping), it's just a wheel balance issue. But, what is the amount of wheel weights per wheel, the 2nd tire shop used to Road/Load Force balance each tire?
A good mount and balance wheel/tire set up will only require minimal amounts of adhesive wheel weights. As little as 1/4 to 1/2 oz and as much as 1.0 to 1.75 oz per wheel. If they needed 2, 3 or 4 oz of wheel weights to balance a single wheel/tire, then remove it, break the bead and rotate the tire 180 degrees. Then remount and balance.
Just a few thoughts, hope some of it will help you to ID the cause.
